  • Product name
    Rabbit IgG, polyclonal - Isotype Control
    See all Rabbit isotype controls
  • Specificity
    This antibody has been selected to be an isotype control as it has no known specificity. Please note that the rabbit IgG Fc region may bind nonspecifically to human tissue. Rabbit IgG is an isotype control used to estimate the non-specific binding of target primary antibodies due to Fc binding or other protein-protein interactions.

  • Histogram showing the fluorescence signal for ADRB2-FITC in PBMCs compared to an Isotype control.

    PBMCs were generated from freshly-drawn blood from healthy human donors. After staining with antibodies against ADRB2 (ab36956) or an isotype control (ab37415), cells were incubated with FITC-labeled secondary anti-rabbit-IgG antibody, and ADRB2 expression was assessed by flow cytometry.

  • ChIP-qPCR for H3K36me2 on the BTF3 locus in NTKO and TKO cells. Methylation enrichment was tested 5 kb upstream of the TSS (5′) and at the TSS (right). ab37415 was used as the isotype contol.
